SPECIFICATION forming part of Letters Patent No. 653,1 12, dated July 3,1900. Application filed March 29,1900; serial No. 10,676. (No model.)

T0 (LZZ whom it may concern.- 1

Be it known that I, TURNER HUNT NANCE, a citizen of the United States,residing at Tale ladega, in the county of Talladega and State ofAlabama, have invented anew and useful Gin-S aw Cleaner, of which thefollowing is a specification.

My invention is an improved gin saw cleaner, one object of my inventionbeing to provide an improved form of cleaning knife or plate which isadapted to be ground and sharpened repeatedly without materiallyreducing its width, and which is of maximum strength and efficiency. n

A further object of my invention is to pro: vide means whereby thecleaning knives or plates may yield in contact with a gin-saw tooth, andthereby avoid breaking the latter.

Myinvention consists of a gin-saw-cleaning knife comprising the platehaving upturnedblades with cutting edges on their upper sides.

My invention further consists in the combination, with a cleaning'knife,of a resilient support therefor,whereby theknife is adapted to yield incontact with a displaced gin-saw tooth. t

In the accompanying drawings, Figure 1 is a front elevation of a portionof a cotton-gin, showing a sectional gin-saw cleaner embodying myimprovements in operative position thereon. Fig. 2 is adiagrammatiotransverse section of the same on a larger scale. Fig. 3 isa perspective view of a section of a sawcleaner embodying myimprovements. Fig. 4 is a detail perspective View of one of thecleaning-knives. Fig. 5 is a detail transverse sectional view of thesame.

For the purposes of this specification I have herein shown my improvedgin-saw cleaner in operative arrangement on a cotton-gin A, the gin-sawsbeing designatedata, the spaceblocks between the gin-saws beingdesignated at b, the saw-shaft at c," and the combs at d.

In the embodiment of my invention for cleaning cotton from the gin-sawsI provide a supporting-bar 1, which may be either coextensive in lengthwith the width of the breast of the cotton-gin or of any appropriatelength, and to the said supporting-bar I secure a series of any desirednumber o f knives 2. I prefer to make the bar 1 of -.woodorothersuitable resilient material for the purpose presently described,and each of my knives comprises a plate 3,which is adapted to be securedtransversely on one side of the bar 1 and to project from the same, asshown. Formed integrally with the projecting portion of the plate 3 onthe sides thereof are upturned blades or flanges 4,which are flaredoutwardly at a suitable angle from the plate 3 and converge toward theouter end of the plate and are provided on their upper sides withbeveled cutting edges 5 at an appropriate angle, and which cutting edgesare adapted to be ground ,and sharpened when the same becomes necessary.It will beobserved by reference to the drawings, more particularly byreference to Figs'.' 4 and 5 thereof, that inasmuch as the upturnedblades 4t project above the face of the plate the cutting edges thereofmay be'repeatedly sharpened from time to time it without materially"reducing the width of the knife or impairing the efficient actionthereof, thus greatly prolonging the life of the knife as compared withthe cleaning knives heretofore employed for this purpose. It will befurther understood that the portion of the plate 3 which bears againstand is secured to the bar 1 forms an elastic bait, and the bar 1 beingresilient, as hereinbefore described, this construction of my improvedgin-saw cleaner provide'selastic supports for the cleaning-knives,whereby the latter are adapted to yield in contact with a displacedgin-saw tooth,and thereby avoid breaking the same from the saw.

In the operation of my invention the bar 1 is placed in position on thegin with the cleaning-knife disposed between the gin-saw and in contacttherewith in the usual manner known to those skilled in this art,and byturning the gin-saws in the reverse direction to that in which theyrotate when in operation the contacting edges 'ofkthe cleaning-knivesagainst the sides of the gin-saw effectually cut and remove the adheringcotton therefrom, thus entirely clearing the teeth of the gin-saws fromthe said adhering cotton.

My improved gin-saw-cleaning knives may be made of malleable ironor'steel plate or of other suitable material, as maybe preferred, and Ido not limit-myself in this particular.

To enable the cleaning-knives to be adjustably secured on the bar 1, Iprovide the latter with a longitudinal slot 7,thr0ugh which boltsthereof, said plate having an extended haft 8, which secure the hafts ofthe knives to the adapted to secure said knife to a suitable supsaidbar, extend, as shown in Figs. 3 and 4. port, substantially asdescribed.
